A kind reader pointed out this unusual signage. He's actually working on creating content for these things and it can display three copies of one 800x600 image around its circumferance. An internal set of LEDs spin around and it can potentially display moving and still images with little flicker.
Cool? Sure. But if we can all figure out how to hack these to show naked pictures of Elton John, then we'd all be in business.
